North Korea ( listen), officially the Democratic People's Republic of Korea (DPRK; Chosŏn'gŭl: 조선민주주의인민공화국), is a country in East Asia, occupying the northern half of the Korean Peninsula. Its capital and largest city is Pyongyang. The Korean Demilitarized Zone serves as the buffer zone between North Korea and South Korea. The Amnok, or Yalu, and the Tumen rivers form the border between North Korea and China. A section of the Tumen River in the far northeast is the border with Russia.

The peninsula was governed by the Korean Empire until it was annexed by Japan after the Russo-Japanese War of 1905. It was divided into Soviet- and American-occupied zones in 1945, after the end of World War II. North Korea refused to participate in a United Nations–supervised election held in the south in 1948, which led to the creation of separate Korean governments for the two occupation zones. North and South Korea each claimed sovereignty over the whole Korean Peninsula, which led to the Korean War of 1950. The Armistice Agreement of 1953 ended the fighting; but the two countries are officially still at war against each other, for a peace treaty was never signed. Both states were accepted into the United Nations in 1991.

Pyongyang (평양, Korean pronunciation: [pʰjɔŋjaŋ], literally: "Flat Land") is the capital of the Democratic People's Republic of Korea, commonly known as North Korea, and the largest city in the country. Pyongyang is located on the Taedong River and, according to preliminary results from the 2008 population census, has a population of 3,255,388. The city was split from the South P'yŏngan province in 1946. It is administered as a directly governed city (chikhalsi), on the same level as provincial governments, not a special city (teukbyeolsi) as Seoul is in South Korea.
